1. Introduction

The Long Range Ethernet Extender, a G.SHDSL (Single-pair High-bit-rate Digital
Subscriber Line) Ethernet Network Extender, provides a broadband full duplex
transmission with bandwidth aggregation up to 10.8Mbps over two pairs of copper
wire for point-to-point LAN connectivity between two Ethernet networks. This is
enough speed to support VoIP, Web hosting, and teleconferencing.

The EIDM-EXTEND-2 conforms to the ITU-T Rec. G.991.2, to meet G.shdsl.bis
network requirements. It offers a cost-effective symmetrical broadband solution for
applications such as LAN to LAN, Internet access, and VoIP. Each Ethernet
Extender can be configured into either STU-C (SHDSL Transceiver Unit) for central
side or STU-R for remote side.

Distances can reach up to 7,000 feet (about 2.1 Km) and 10,000 feet (about 3 Km) at
the maximum rate of 10.8 Mbps and 9.216Mbps with two pairs of 24AWG (0.5 mm)
copper wire, and could reach 20,500 feet (about 6.2 Km) at 192Kbps. Users can also
select a fixed data rate for the copper lines ranging from 192Kbps to 10.8Mbps. The
Ethernet Extender provides a console port for users to configure the settings and to
monitor the connection status.

5. Installation Procedures

Step 1: Connect the SHDSL line (1 or 2 pairs) to the RJ-48 connector (marked Line) on

the rear panel of the Ethernet Extender.

Please note: RJ-48 and RJ-45 connectors are physically identical

RJ-48 Connector Pin Assignment for SHDSL Line Interface, straight through

Note: RJ48 connectors hold up to eight wires. They use the same plug and socket as an RJ-45 but have

different pin-outs. RJ-48C is commonly used for T1 lines and uses pins 1, 2, 4 and 5.

Step 2: Connect the Ethernet interface to the RJ-45 Port(s) (marked LAN1 and LAN2)

with the included CAT5 cable.

Step 3: Connect both Ethernet Extenders to the AC outlet using the power cords

included and turn on the power switch.

Step 4: Please refer to the Console Port Control section for initial serial interface setup.

Set one Ethernet Extender as STU-C (Central) from console port, and the other
Extender as STU-R (Remote). Type 1 in the Main Menu to select Configuration
menu, then type 1 in the Configuration menu to select DSL Mode. Make sure one
unit is STU-C and the other is STU-R. Extenders will automatically connect with
each other. There will be 2 or more handshaking cycles when Adaptive is selected
as the speed setting. The system will adapt to the maximum rate possible
according to the loop distance. The maximum Adaptive rates are 4,608Kbps for
single pair and 9,216Kbps for two pair mode. The maximum fixed rate is

10.8Mbps.

6. Front Panel LED Indicators

There are 8 LED indicators on the front panel of the Long Range Ethernet Extender
displaying the current status. These LED indicators are described as following.

POWER: “Green On” shows Ethernet Extender power supply is normal.

TEST : “Yellow On” shows Ethernet Extender is self testing after powered on.
LOOP1 : “Green Flash” shows SHDSL connection is in progress.

：“Green On” shows SHDSL loop1 connects successfully.
LOOP2 : “Green Flash” shows SHDSL connection is in progress.

: “Green On” shows SHDSL loop2 connects successfully.
LAN1 : “Green On” shows LAN1 port is in connection.
： “Green Flash” shows data activity on LAN1 port.

100 : “Green On” shows LAN1 Ethernet connection is at 100Mbps.
LAN2 : “Green On” shows LAN2 port is in connection.
： “Green Flash” shows data activity on LAN2 port.

100 : “Green On” shows LAN2 Ethernet connection is at 100Mbps.
